3M™ Peltor™ Optime™ 98 Earmuffs – H9A Over-the-Head Style

The 3M™ H9A Optime™ 98 Earmuffs are versatile, high-performance hearing protection designed for noise levels up to 98 dBA. These earmuffs combine rugged durability with advanced comfort features, utilizing a robust stainless steel headband to ensure a consistent, secure fit and effective noise reduction throughout the workday.

Key Features & Benefits

• High NRR Protection: Achieves a Noise Reduction Rating (NRR) of 25 dB*, providing robust protection in moderate-to-high noise environments.

• Durable Headband: The stainless steel headband construction resists bending, warping, and corrosion, ensuring long-lasting performance and consistent clamping force.

• Optimized Comfort: Earcup pivot points tilt for optimal fit and efficiency, while ultra-lightweight liquid/foam-filled cushions create a comfortable, low-pressure seal.

• Compliance Sighting: Features color-coding for easy visual verification by safety officers that the correct protective equipment is being worn.

• Versatile Design: The over-the-head style is a classic design that is easy to wear and compatible with many other forms of personal protective equipment (PPE).

*The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided in real-world applications.

Ideal Applications

The 3M H9A earmuffs are highly recommended for use in:

• Heavy Machinery Operation: Around loaders, excavators, and generators.

• Industrial Manufacturing: Stamping presses, textile equipment, and general factory noise.

• Aviation & Automotive: Maintenance hangars and production facilities.

• Utility Work: Environments involving power tools and high-volume noise sources.
